Variation of energy absorption buildup factors with incident photon energy and penetration depth for some commonly used solvents

G.P. fitting method has been used to compute energy absorption buildup factor of some commonly used solvents such as acetonitrile (C4H3N), butanol (C4H9OH), chlorobenzene (C6H5Cl), diethyl ether (C4H10O), ethanol (C2H5OH), methanol (CH3OH), propanol (C3H7OH) and water (H2O) for the wide energy range (0.015-15.0 MeV) up to the penetration depth of 10 mean free path. The variation of energy absorption buildup factor with chemical composition as well as incident photon energy for the selected solvents has been studied. It has been observed that the maximum value of energy absorption buildup factors shifts to the slightly higher incident photon energy with the increase in equivalent atomic number of the solvent and the solvent with least equivalent atomic number possesses the maximum value of energy absorption buildup factor.
